Bug fix for NumTraits<T>::lowest() .
...
std::numeric_limits<T>::min() is the lowest *positive* normalized number
for floating point types.
This fixes the test failure for geo_alignedbox8 for me.

Remove \nonstable yet. The stability rules for Eigen3 are much simpler:

- all what's not in unsupported/ is considered stable API
(except internal stuff e.g. expression templates).

fix #126 , part 2/2: the checkTransposeAliasing() assertion was always compiled, for all expressions,
...
even for expressions that are known at compile time to not need it because they don't involve any transposing.
This gave 'controlling condition is constant' warnings on ICC, and potentially worse, this could generate a lot
of useless code per-expression if the compiler failed to realize that the condition was constant.
